Ball mill driving system introduction-main shaft and the main bearing

Ball mill Main shaft and the main bearing: ball mill main shaft bear all the load from outside, and load the main bearing, and then pass to the foundation. It is the main part. The main shaft install on the sliding bearing which fix on the foundation or the machine base. Generally, the main shaft adopt two supporting point, main shaft and the gearbox connected by the gear coupling,gear coupling only pass the torque,can’t pass bending moment,therefore, main shaft is two fulcrum in the statically determinate structure.At the same time, Because a gear coupling allow main shaft some tilt, therefor is greatly improved the spindle assembly.
